Construction Costs of Various Bridge Types





Final Result

The path with the lowest friction value was the Cost Path to proposed bridge site 1 and the cheapest bridge type to construct is a bascule bridge and it of course costs less to construct a smaller bridge. Overall it appears that the lower friction value for the Cost Path doesn’t make up for the fact that to construct a larger bridge the cost is much greater and thus the best solution appears to be to use the Cost Path to proposed bridge site 2 and to construct a bascule bridge.
